摘要
文章分析室内长期老化模拟试验对沥青及沥青砂浆力学响应的影响。室内长期老化模拟试验采用了1000h的紫外光、热氧及湿气共同作用下的加速老化试验。在DSR动态剪切流变仪的基础上开发了成套适用于沥青砂浆试验平台。利用动态剪切模量和相位角主曲线分析了室内长期老化模拟试验对沥青及其砂浆力学响应的影响。
This paper investigates the effect of laboratory long-term aging simulation testing on response properties of bituminous mortar. The long-term aging regime consists of a 1000-hour aging by using a combination of ultraviolet aging, thermal aging as well as the effect of humidity and oxygen. A complete set of test platform was developed for bituminous mortar on the basis of dynamic shear rheometer. The effect of laboratory long-term aging simulation testing is discussed by means of the master curves of complex modulus and phase angle.
